Summary

Google PM interview with a meaty product design question around enterprise finance automation. Single question but it had a lot of layers and I wasn't fully prepared for how deep they wanted to go on the exceptions side.

Questions Asked (1)

Q1

Design a product that automates three-way matching in a Procure-to-Pay workflow, including how the system handles exceptions.

Suggested Approach

Start by clarifying the P2P workflow and the goal of three-way matching (PO, GRN, Invoice) to ensure alignment. Then, outline the product vision, key features, and how automation and exception handling will work. Finally, discuss success metrics and potential challenges.

Pro tip: Emphasize that exception handling is not just about error resolution but also about learning and improving the matching algorithm over time. Show how you'd prioritize exceptions based on business impact and frequency.

1. Clarify and Define

Ask clarifying questions to understand the current P2P process, pain points, and the specific goals of automating three-way matching. Define what success looks like.

2. Product Vision and Features

Describe the product's core functionality: automated matching of PO, GRN, and Invoice, with configurable tolerance rules. Highlight key features like real-time matching, integration with ERP, and user roles.

3. Exception Handling Design

Detail how the system detects, categorizes, and routes exceptions (e.g., price mismatch, quantity mismatch, missing documents). Explain workflows for resolution, including automated suggestions and manual review.

4. Metrics and Iteration

Propose metrics to measure success (e.g., match rate, exception resolution time, cost savings). Discuss how to use data to continuously improve the matching logic and exception handling.

5. Risks and Mitigations

Identify potential risks (e.g., data quality, change management, integration complexity) and propose mitigation strategies.

Key Points to Mention

  • Three-way matching: Purchase Order, Goods Receipt Note, Invoice
  • Tolerance rules and configurable thresholds
  • Exception categorization: price, quantity, tax, missing documents
  • Automated exception resolution suggestions (e.g., auto-approve within tolerance)
  • Integration with ERP and other systems (e.g., SAP, Oracle)
  • Metrics: match rate, exception rate, resolution time, cost per invoice
